Answer #1
Concepts and reason

Cyclohexane is more stable in its chair conformation. In chair conformation of cyclohexane, two types of groups are present at each carbon atom. They are axial groups and equatorial groups.

Fundamentals

If two substituents are cis to each other then they are in up, up (or) down, down to each other in chair conformation.

Bulky groups present in equatorial positions will make the chair conformation most stable. If the bulky groups present in axial positions, then 1,3-diaxial interactions will make the chair conformation less stable.
